RewritePrompt

The constrained-rewrite prompt for the LLM formatter (consumed by the Candle façade in T7). system is hard restraint that holds at every level; the per-level rule only widens which edits are permitted. Restraint is the wording, so it lives here in the pure core, not in the inference façade.

Enums

Level

Cleanup intensity. Plan 3 wires this into the LLM rewrite; deterministic-Light is the instant, always-present layer.

Functions

apply_backtrack

Remove a self-correction: when a backtrack trigger appears AS A WHOLE PHRASE, drop the words immediately preceding it (the spec’s >3-word-reduction guard: only fire when at least 3 words precede the trigger, so we don’t nuke a short true clause). Word-bounded so it never deletes content words it matched inside.

apply_spoken_commands

Apply spoken formatting commands deterministically. Padding the input with spaces lets a command at the phrase start or end match too (the replacements are space-delimited). Note: back-to-back identical commands (“new line new line”) collapse to one — an accepted Plan-1 edge case.

decapitalize_continuation

Lowercase the first letter of text when it CONTINUES the previous block — the previous block didn’t end a sentence (no terminal .!?) AND the first word is an allow-listed continuation word. Whisper cases each segment as a fresh sentence; this undoes the spurious mid-sentence capital when a sentence spans a pause. Conservative by construction (only the allow-list; never a proper noun).

deterministic_light

Deterministic “Light”: capitalize sentence starts, ensure terminal punctuation, strip leading fillers. Always guard-safe by construction.

format_revise

Format a pass-2 Whisper revise. Whisper already cased + punctuated, so this does NOT re-capitalize sentence starts or force terminal punctuation (that re-creates the per-segment mid-sentence capital). It applies only the spoken-command and scratch that backtrack features and the continuation de-capitalizer.

guard_accepts

The moat: accept a rewrite only if it preserves every content word from the input, in order, adding/removing nothing but allowed fillers. Guards harm (a substituted/dropped meaning word) rather than edit volume.

parse_level

Parse a config string into a Level (defaults to Light — the safe, restrained default — on anything unrecognized).

rewrite_prompt

Build the per-level rewrite prompt for T7’s Candle façade. The Light rule keeps filler removal to LEADING disfluencies only — mid-sentence you know/i mean removal is deliberately NOT requested, because the content-word guard would accept such drops (see the FILLERS note). T7 must preserve this restriction.
